duct silencer

sound attenuator

In ductwork, a device (usually prefabricated) especially designed to provide much greater sound attenuation than would be provided by an equal length of ductwork; the pressure drop through the device is greater than for an equal length of ductwork.

The work will include the wind tunnel ducting, fan and drive system, in-line heat exchanger (to couple with the building chiller system), turning vanes, duct silencers and necessary honeycomb and screens.
